Definitions
- the present invention relates to a shooting game system and an external storage used therefor. More particularly, it relates to a shooting game system so adapted as to display a target on a raster scan type display and shoot the target displayed with a shooting scope and an external storage used therefor.
- a shooting game system so adapted as to shoot a target displayed on a television receiver with a shooting scope
- a shooting game system disclosed in U. S. Patent No. 4, 395, 045 (hereinafter referred to as first prior art) and a shooting game system disclosed in Japanese Patent Laid-Open Gazette No. 171063/1985 (corresponding U. S. Patent No. 4, 813, 682) (hereinafter referred to as second prior art) have been conventionally known.
- an image of a target displayed on a television receiver is detected on the side of a shooting scope, and its detection pulse is transmitted to a computer connected to the television receiver.
- the computer detects a coordinate position which is shot on the screen of the television receiver on the basis of the phase difference between the detection pulse received and synchronizing signals (horizontal and vertical synchronizing signals) of the television receiver.
- the above described second prior art is so adapted as to display a character of a target in white and a background in black when a trigger switch of a shooting scope is depressed, and make hit judgment depending on whether or not an image of this character is detected by the shooting scope.
- the first prior art is so adapted as to correct the coordinate position which is shot by the shooting scope on the screen of the television receiver when hit judgment is made.
- the reason for this is that an optical axis of the barrel of the shooting scope and a sighting axis of a gunsight do not exist on the same straight line, so that there occurs a shift between the optical axis and the sighting axis on the screen of the television receiver.
- this correction processing is performed using a fixed correction value.
- the first prior art has the disadvantage in that no ideal correction can be made and inaccurate hit judgment is made in cases, for example, where an angle at which a player looks into the gunsight deviates from a previously presumed angle or an angle which the optical axis of the barrel forms with the sighting axis of the gunsight deviates from a previously presumed angle due to a manufacturing error, and the distance between the television receiver and the shooting scope deviates from a previously presumed distance.
- the first prior art also has the disadvantage in that an optical system provided for the shooting scope and an optical system provided for the computer are easily adversely affected by disturbance light from the exterior (for example, one due to illuminating light of a fluorescent lamp or the like and one due to substantial adjustment of the luminance of the television receiver), and an error is liable to occur in detection of a light receiving signal from the target of the television receiver.
- the second prior art has the disadvantage in that the precision of hit judgment is low when a small target is shot because a coordinate position which is shot by the shooting scope can be only detected for each character.
- the second prior art has the disadvantage in that no accurate hit judgment can be made when an optical axis of the barrel of the shooting scope and a sighting axis of a gunsight are shifted because the coordinate position which is shot is not corrected.
- an object of the present invention is to provide a shooting game system capable of detecting even a small target such as a dot unit with high precision.
- Another object of the present invention is to provide a shooting game system which is not easily adversely affected by disturbance light from the exterior and always allows high-precision detection.
- Still another object of the present invention is to provide a new external storage used for a shooting game system.
- the present invention provides a shooting game system for shooting a target displayed on a raster scan type display in a position spaced apart from the display to play a shooting game, which comprises a game processing apparatus used with it being connected to the display for performing processing for the shooting game, and a shooting scope used in a position spaced apart from the display and for shooting the target displayed on the display.
- the shooting scope comprises trigger signal generating means, photoelectric converting means, and control signal transmitting means.
- the trigger signal generating means generates a trigger signal in response to an operation performed by a player.
- the photoelectric converting means converts light from a position which is shot on the display into an electric signal which is synchronized with raster scanning of the display.
- the control signal transmitting means transmits a control signal based on the electric signal outputted from the photoelectric converting means to the game processing apparatus in response to the trigger signal from the trigger signal generating means.
- the game processing apparatus comprises control signal receiving means, shot coordinate position detecting means, reference mark display controlling means, error operating means, error storing means, target display controlling means, correcting means, and hit judging means.
- the control signal- receiving means receives the control signal transmitted from the control signal transmitting means.
- the shot coordinate position detecting means detects a coordinate position which is shot by the shooting scope on the display on the basis of the control signal received by the control signal receiving means.
- the reference mark display controlling means displays a reference mark in a predetermined fixed position on the display before starting the game.
- the error operating means operates, when the reference mark is shot by the shooting scope, an error between the coordinate position detected by the shot coordinate position detecting means and a coordinate position of the reference mark.
- the error storing means stores the error operated by the error operating means.
- the target display controlling means displays the target on the display while the game is played.
- the correcting means corrects, when the target on the display is shot by the shooting scope, the relative positional relationship between a coordinate position of the target and the coordinate position detected by the shot coordinate position detecting means on the basis of the error stored in the error storing means.
- the hit judging means makes hit judgment in a case where the target is shot by the shooting scope on the basis of the relative positional relationship after being corrected by the correcting means.
- the reference mark is displayed on the display before starting the game, the error between the coordinate position which is shot by the shooting scope on the display and the coordinate position of the reference mark is previously operated, and the relative positional relationship between the coordinate position which is shot by the shooting scope on the display and the coordinate position of the target displayed on the display is corrected on the basis of the above described error operated when the game is played. Accordingly, fine correction can be made in consideration of various factors (the change in distance between the display and the shooting scope, a player's habit, the variation in properties of products, and the like). Consequently, more accurate correction can be always made, as compared with the conventional case where correction is made on the basis of a fixed correction value, to allow accurate sighting and hit judgment.
- only the control signal transmitted by the control signal transmitting means is extracted from a receiving signal of the control signal receiving means on the basis of the periodicity of a plurality of pulse signals included in the receiving signal, and the coordinate position which is shot by the above described shooting scope on the above described display is detected on the basis of this control signal extracted, thereby to make it possible to prevent a malfunction due to the disturbance light or the like.
- An external storage is used for a shooting game system comprising a game processing apparatus connected to a raster scan type display, and a shooting scope used in a position spaced apart from the display and for shooting a target displayed on the display, and is relevantly connected to the game processing apparatus.
- the shooting scope comprises trigger signal generating means for generating a trigger signal in response to an operation performed by a player, photoelectric converting means for converting light from a position which is shot on the display into an electric signal which is synchronized with raster scanning of the display, and control signal transmitting means for transmitting a control signal based on the electric signal outputted from the photoelectric converting means to the game processing apparatus in response to the trigger signal from the trigger signal generating means.
- the game processing apparatus comprises information processing means for performing predetermined processing for the shooting game in accordance with program data applied from the external storage, and control signal receiving means for receiving the control signal transmitted from the control signal transmitting means.
- the external storage comprises first to sixth program storing means and error storing means.
- the first program storing means stores first program data for detecting a coordinate position which is shot by the shooting scope on the display on the basis of the control signal received by the control signal receiving means.
- the second program storing means stores second program data for displaying a reference mark in a predetermined fixed position on the display before starting the game.
- the third program storing means stores third program data for operating, when the reference mark is shoot by the shooting scope, an error between the coordinate position detected in accordance with the first program data and a coordinate position of the reference mark.
- the error storing means stores the error operated in accordance with the third program data.
- the fourth program storing means stores fourth program data for displaying the target on the display while the game is played.
- the fifth program storing means stores fifth program data for correcting, when the target on the display is shot by the shooting scope, the relative positional relationship between a coordinate position of the target and the coordinate position detected in accordance with the first program data on the basis of the error stored in the error storing means.
- the sixth program storing means stores sixth program data for making hit judgment in a case where the target is shot by the shooting scope on the basis of the relative positional relationship after being corrected in accordance with the fifth program data.

- the video game set 1 is further connected to a television receiver 4 and displays images of a target, a background and the like for a game on the television receiver 4 on the basis of the program data.
- an optical disk may be used in place of the ROM cartridge 2 as means for storing program data.
- an optical disk recording and reproducing apparatus for reading recorded data of the optical disk is connected to the video game set 1 to transfer the program data read by the optical disk recording and reproducing apparatus.
- a control signal is converted into a light signal of infrared rays or the like to be transmitted to the receiver 3 in response to operations of a plurality of switches provided in an approximately central part in the longitudinal direction of the shooting scope 5.
- the video game set 1 changes image display and outputs voice in conformity to the progress of the game on the basis of the program data in response to the signal from the receiver 3.
- a gunsight 10 mounted on the upper part of the barrel 8 is so detachably constructed that it can be mounted on the right or left side to suit to player's own convenience.
- Figs. 2, 3 and 4 are respectively a right side view, a left side view and a rear elevation illustrating the shooting scope 5 used in one embodiment of the present invention. Referring now to Figs. 2 to 4, description is made of the structure of the appearance of the shooting scope 5.
- a stock 7 is provided beneath the rear in the longitudinal direction of a barrel 8.
- a grip 6 is provided beneath the front in the longitudinal direction of the barrel 8.
- a gunsight 10 is detachably mounted on the upper front part in the longitudinal direction of the barrel 8.
- a trigger switch SW1, a pause switch SW2, and a power supply/continuous shooting switch SW3 are provided in an approximately central part of the barrel 8 and in the rear of the gunsight 10.
- the trigger switch SW1 and the pause switch SW2 are constructed as push button switches, and the power supply/continuous shooting switch SW3 is constructed as a slide switch.
- the trigger switch SW1 generates a single shooting signal every time it is depressed in a state where the power supply/continuous shooting switch SW3 as described water is in a second stopped position, and continuously generates a shooting signal in a time period during which it is depressed in a state where the power supply/continuous shooting switch SW3 is in a third stopped position.
- the pause switch SW2 generates a pause signal when it is depressed.
- the power supply/continuous shooting switch SW3 has three stopped positions, and gives a command to turn the power supply off in the first stopped position, to turn the power supply on in the second stopped position, and to select a continuous shooting mode in the third stopped position.
- a cursor switch SW4 is provided on the rear side surface of the grip 6.
- This cursor switch SW4 generates a display command signal of a cursor when it is depressed.
- the gunsight 10 comprises a mount 12, and a scope 13 and a foresight 14 which are held on this mount 12.
- the mount 12 is fixedly held on the barrel 8 by engaging claws 15 and 16 formed in the barrel 8.
- the mount 12 is so locked by a locking claw 17 formed in the barrel 8 that it does not slip off the engaging claws 15 and 16.
- engaging claws 15 and 16 and the locking claw 17 are provided in the upper right front part in the longitudinal direction of the barrel 8 (on the right side as viewed from a muzzle 9), similar engaging claws 18 and 19 and locking claw 20 are provided in the upper left part of the barrel 8 (see Fig. 3).
- the engaging claws 15 and 16 and the locking claw 17 and the engaging claws 18 and 19 and the locking claw 20 are provided in positions symmetrical with respect to an optical axis of the barrel 8.
- the gunsight 10 may be detached from the engaging claws 15 and 16 and mounted on the engaging claws 18 and 19.
- a position where the gunsight 10 is mounted can be thus changed to the most suitable position depending on whether a user of the shooting scope is right-handed or left-handed. Consequently, it is possible to obtain a shooting scope significantly superior in operability.
- the shooting scope 5 As shown in Fig. 5, the shooting scope 5 according to the present embodiment is generally used in a position close to, that is, spaced approximately 3 meters apart from the television receiver 4. Consequently, if a sighting axis and the optical axis are parallel to each other, coordinates on the television screen of an extension line of the sighting axis and an extension line of the optical axis are considerably shifted. In the present embodiment, therefore, the shooting scope 5 is so constructed that when the gunsight 10 is mounted on the barrel 8, the gunsight 10 makes a predetermined angle to the optical axis such that the sighting axis crosses an optical axis of a condenser lens 31 (see Fig.
- the gunsight 10 is so selected that the sighting axis in a case where the foresight 14 is looked into from the scope 13 is slightly downward with respect to the bottom surface of the mount 12, and is mounted on the upper part of the barrel 8 and a position at an angle of 45° on the left or right side to the vertical axis passing through the optical axis.
- the optical axis and the sighting axis can be made to cross (or concentrated on one point) on the screen of the television receiver 4 a predetermined distance ahead of the muzzle 9, thereby to make it possible to shoot the target accurately and with high precision.
- the gunsight 10 is detachably constructed in the position at an angle of 45° on the right or left side to the optical axis, a player can surely aim at the target irrespective of the dominant hand, the dominant eye and the size of a player's face, thereby to make it possible to further improve the operability.
- Fig. 6 is a block diagram showing the inner structure of the shooting scope 5 shown in Fig. 1.
- the shooting scope 5 comprises a lens 31, slits 32 and 33, an infrared cut filter 34, a light receiving element 35, a pre-amplifier 36, a high-pass filter 37, a waveform shaping circuit 38, an AND gate 39, an OR gate 40, a driver 41, infrared LED (light emitting diode) 42, AND gates 43 and 44, a monostable multivibrator 45, an oscillator 46, an oscillator 47, a monostable multivibrator 48, an encoder 49, monostable multivibrators 51 to 54, and a OR gate 55.
- the lens 31 is provided in the vicinity of the muzzle 9 and forms an image of a target displayed on the television receiver 4 on the light receiving element 35.
- the slits 32 and 33 are used for eliminating undesired disturbance light from the exterior, and the inner diameter of the slit 33 is selected to be smaller than the inner diameter of the slit 32.
- the infrared cut filter 34 is used for preventing infrared rays from being incident on the light receiving element 35.
- the light receiving element 35 includes, for example, a photodiode, and detects a light signal from the target displayed on the television receiver 4 and converts the same into an electric signal. A detection signal of the light receiving element 35 is amplified by the pre-amplifier 36 and then, is applied to the high-pass filter 37.
- the high-pass filter 37 eliminates disturbance signals other than objective signals, for example, signals of sunlight, illuminating light and the like.
- An output of the high-pass filter 37 is subjected to waveform shaping by the waveform shaping circuit 38 and is converted into a pulse signal and then, is applied to the AND gate 39.
- An output of the AND gate 39 is applied to the driver 41 through the OR gate 40.
- the driver 41 is used for driving the infrared LED 42.
- the infrared LED 42 is provided inside of an infrared device 11 and sends out an infrared signal to the receiver 3.
- a trigger signal based on an operation of the trigger switch SW1 is applied to the AND gate 43 and is applied to the AND gate 44 after being inverted.
- a continuous shooting signal based on the power supply/continuous shooting switch SW3 is applied to the AND gate 44 and is applied to the AND gate 43 after being inverted.
- a cursor signal based on the cursor switch SW4 is applied to the oscillator 47.
- a pause signal based on the pause switch SW2 is applied to the monostable multivibrator 48.
- Respective outputs of the monostable multivibrator 45, the oscillators 46 and 47 and the monostable multivibrator 48 are applied to the encoder 49,
- the encoder 49 encodes the respective signals inputted An output of the encoder 49 is applied to the OR gate 40.
- the output of the monostable multivibrator 45 is further applied to the monostable multivibrator 53 and is applied to the monostable multivibrator 51 through the OR gate 50.
- the output of the oscillator 46 is further applied to the monostable multivibrator 51 through the OR gate 50.

- Outputs of the monostable multivibrators 52 and 54 are applied to the AND gate 39 through the OR gate 55.
- the shooting scope 5 Description is now made of the operation of the shooting scope 5.
- a player carries the shooting scope 5 on his shoulder, and looks into the gunsight 10 to sight a target on the television screen,
- the lens 31 collects light on an image on the television screen in the vicinity of the optical axis of the barrel 8 and forms the image on the light receiving element 35. Consequently, the light receiving element 35 converts a light signal from the image in the vicinity of a portion to which the muzzle 9 is directed on the television screen (not the entire screen) into an electric signal and outputs the same.
- the output of the light receiving element 35 is subjected to amplification, noise removal and waveform shaping by the pre-amplifier 36, the high-pass filter 37 and the waveform shaping circuit 38 and is converted into a pulse signal.
- the light receiving element 35 outputs a detection signal every time a scanning line, that is, a raster passes through a region where the lens 31 collects light on the television screen. Accordingly, an output of the waveform shaping circuit 38 becomes a pulse train of raster pulses having a period according to the horizontal frequency of a television video signal (hereinafter referred to as a raster pulse train). This raster pulse train is shown in Fig. 7 (b).
- a trigger signal at a high level is outputted from this trigger switch SW1 and is applied to the monostable multivibrator 45 through the AND gate 43.
- the monostable multivibrator 45 outputs one pulse signal in response to this trigger signal.
- This pulse signal is applied to the encoder 49 to be encoded.
- the encoder 49 generates a trigger code as shown in Fig. 7 (a).
- This trigger code is applied to the driver 41 through the OR gate 40.
- the driver 41 drives the infrared rays LED 42 on the basis of the trigger code applied. Consequently, a trigger code serving as an infrared signal is outputted from the infrared LED 42, as shown in Fig. 7 (c).

Abstract
Description
- The present invention relates to a shooting game system and an external storage used therefor. More particularly, it relates to a shooting game system so adapted as to display a target on a raster scan type display and shoot the target displayed with a shooting scope and an external storage used therefor.
- As a shooting game system so adapted as to shoot a target displayed on a television receiver with a shooting scope, a shooting game system disclosed in U. S. Patent No. 4, 395, 045 (hereinafter referred to as first prior art) and a shooting game system disclosed in Japanese Patent Laid-Open Gazette No. 171063/1985 (corresponding U. S. Patent No. 4, 813, 682) (hereinafter referred to as second prior art) have been conventionally known.
- In the above described first prior art, an image of a target displayed on a television receiver is detected on the side of a shooting scope, and its detection pulse is transmitted to a computer connected to the television receiver. The computer detects a coordinate position which is shot on the screen of the television receiver on the basis of the phase difference between the detection pulse received and synchronizing signals (horizontal and vertical synchronizing signals) of the television receiver.
- The above described second prior art is so adapted as to display a character of a target in white and a background in black when a trigger switch of a shooting scope is depressed, and make hit judgment depending on whether or not an image of this character is detected by the shooting scope.
- The first prior art is so adapted as to correct the coordinate position which is shot by the shooting scope on the screen of the television receiver when hit judgment is made. The reason for this is that an optical axis of the barrel of the shooting scope and a sighting axis of a gunsight do not exist on the same straight line, so that there occurs a shift between the optical axis and the sighting axis on the screen of the television receiver. However, this correction processing is performed using a fixed correction value. Therefore, the first prior art has the disadvantage in that no ideal correction can be made and inaccurate hit judgment is made in cases, for example, where an angle at which a player looks into the gunsight deviates from a previously presumed angle or an angle which the optical axis of the barrel forms with the sighting axis of the gunsight deviates from a previously presumed angle due to a manufacturing error, and the distance between the television receiver and the shooting scope deviates from a previously presumed distance.
- Furthermore, the first prior art also has the disadvantage in that an optical system provided for the shooting scope and an optical system provided for the computer are easily adversely affected by disturbance light from the exterior (for example, one due to illuminating light of a fluorescent lamp or the like and one due to substantial adjustment of the luminance of the television receiver), and an error is liable to occur in detection of a light receiving signal from the target of the television receiver.
- On the other hand, the second prior art has the disadvantage in that the precision of hit judgment is low when a small target is shot because a coordinate position which is shot by the shooting scope can be only detected for each character.
- Furthermore, the second prior art has the disadvantage in that no accurate hit judgment can be made when an optical axis of the barrel of the shooting scope and a sighting axis of a gunsight are shifted because the coordinate position which is shot is not corrected.
- Therefore, an object of the present invention is to provide a shooting game system capable of detecting even a small target such as a dot unit with high precision.
- Another object of the present invention is to provide a shooting game system which is not easily adversely affected by disturbance light from the exterior and always allows high-precision detection.
- Still another object of the present invention is to provide a new external storage used for a shooting game system.
- The present invention provides a shooting game system for shooting a target displayed on a raster scan type display in a position spaced apart from the display to play a shooting game, which comprises a game processing apparatus used with it being connected to the display for performing processing for the shooting game, and a shooting scope used in a position spaced apart from the display and for shooting the target displayed on the display. The shooting scope comprises trigger signal generating means, photoelectric converting means, and control signal transmitting means. The trigger signal generating means generates a trigger signal in response to an operation performed by a player. The photoelectric converting means converts light from a position which is shot on the display into an electric signal which is synchronized with raster scanning of the display. The control signal transmitting means transmits a control signal based on the electric signal outputted from the photoelectric converting means to the game processing apparatus in response to the trigger signal from the trigger signal generating means. The game processing apparatus comprises control signal receiving means, shot coordinate position detecting means, reference mark display controlling means, error operating means, error storing means, target display controlling means, correcting means, and hit judging means. The control signal- receiving means receives the control signal transmitted from the control signal transmitting means. The shot coordinate position detecting means detects a coordinate position which is shot by the shooting scope on the display on the basis of the control signal received by the control signal receiving means. The reference mark display controlling means displays a reference mark in a predetermined fixed position on the display before starting the game. The error operating means operates, when the reference mark is shot by the shooting scope, an error between the coordinate position detected by the shot coordinate position detecting means and a coordinate position of the reference mark. The error storing means stores the error operated by the error operating means. The target display controlling means displays the target on the display while the game is played. The correcting means corrects, when the target on the display is shot by the shooting scope, the relative positional relationship between a coordinate position of the target and the coordinate position detected by the shot coordinate position detecting means on the basis of the error stored in the error storing means. The hit judging means makes hit judgment in a case where the target is shot by the shooting scope on the basis of the relative positional relationship after being corrected by the correcting means.
- According to the present invention, the reference mark is displayed on the display before starting the game, the error between the coordinate position which is shot by the shooting scope on the display and the coordinate position of the reference mark is previously operated, and the relative positional relationship between the coordinate position which is shot by the shooting scope on the display and the coordinate position of the target displayed on the display is corrected on the basis of the above described error operated when the game is played. Accordingly, fine correction can be made in consideration of various factors (the change in distance between the display and the shooting scope, a player's habit, the variation in properties of products, and the like). Consequently, more accurate correction can be always made, as compared with the conventional case where correction is made on the basis of a fixed correction value, to allow accurate sighting and hit judgment.
- According to another aspect of the present invention, only the control signal transmitted by the control signal transmitting means is extracted from a receiving signal of the control signal receiving means on the basis of the periodicity of a plurality of pulse signals included in the receiving signal, and the coordinate position which is shot by the above described shooting scope on the above described display is detected on the basis of this control signal extracted, thereby to make it possible to prevent a malfunction due to the disturbance light or the like.
- An external storage according to the present invention is used for a shooting game system comprising a game processing apparatus connected to a raster scan type display, and a shooting scope used in a position spaced apart from the display and for shooting a target displayed on the display, and is relevantly connected to the game processing apparatus. The shooting scope comprises trigger signal generating means for generating a trigger signal in response to an operation performed by a player, photoelectric converting means for converting light from a position which is shot on the display into an electric signal which is synchronized with raster scanning of the display, and control signal transmitting means for transmitting a control signal based on the electric signal outputted from the photoelectric converting means to the game processing apparatus in response to the trigger signal from the trigger signal generating means. The game processing apparatus comprises information processing means for performing predetermined processing for the shooting game in accordance with program data applied from the external storage, and control signal receiving means for receiving the control signal transmitted from the control signal transmitting means. The external storage. comprises first to sixth program storing means and error storing means. The first program storing means stores first program data for detecting a coordinate position which is shot by the shooting scope on the display on the basis of the control signal received by the control signal receiving means. The second program storing means stores second program data for displaying a reference mark in a predetermined fixed position on the display before starting the game. The third program storing means stores third program data for operating, when the reference mark is shoot by the shooting scope, an error between the coordinate position detected in accordance with the first program data and a coordinate position of the reference mark. The error storing means stores the error operated in accordance with the third program data. The fourth program storing means stores fourth program data for displaying the target on the display while the game is played. The fifth program storing means stores fifth program data for correcting, when the target on the display is shot by the shooting scope, the relative positional relationship between a coordinate position of the target and the coordinate position detected in accordance with the first program data on the basis of the error stored in the error storing means. The sixth program storing means stores sixth program data for making hit judgment in a case where the target is shot by the shooting scope on the basis of the relative positional relationship after being corrected in accordance with the fifth program data.

A control signal is converted into a light signal of infrared rays or the like to be transmitted to thereceiver 3 in response to operations of a plurality of switches provided in an approximately central part in the longitudinal direction of theshooting scope 5. The video game set 1 changes image display and outputs voice in conformity to the progress of the game on the basis of the program data in response to the signal from thereceiver 3. - A
gunsight 10 mounted on the upper part of thebarrel 8 is so detachably constructed that it can be mounted on the right or left side to suit to player's own convenience. - Figs. 2, 3 and 4 are respectively a right side view, a left side view and a rear elevation illustrating the
shooting scope 5 used in one embodiment of the present invention. Referring now to Figs. 2 to 4, description is made of the structure of the appearance of theshooting scope 5. - A
stock 7 is provided beneath the rear in the longitudinal direction of abarrel 8. In addition, agrip 6 is provided beneath the front in the longitudinal direction of thebarrel 8. Further, agunsight 10 is detachably mounted on the upper front part in the longitudinal direction of thebarrel 8. A trigger switch SW1, a pause switch SW2, and a power supply/continuous shooting switch SW3 are provided in an approximately central part of thebarrel 8 and in the rear of thegunsight 10. The trigger switch SW1 and the pause switch SW2 are constructed as push button switches, and the power supply/continuous shooting switch SW3 is constructed as a slide switch. The trigger switch SW1 generates a single shooting signal every time it is depressed in a state where the power supply/continuous shooting switch SW3 as described water is in a second stopped position, and continuously generates a shooting signal in a time period during which it is depressed in a state where the power supply/continuous shooting switch SW3 is in a third stopped position. The pause switch SW2 generates a pause signal when it is depressed. The power supply/continuous shooting switch SW3 has three stopped positions, and gives a command to turn the power supply off in the first stopped position, to turn the power supply on in the second stopped position, and to select a continuous shooting mode in the third stopped position. A cursor switch SW4 is provided on the rear side surface of thegrip 6. This cursor switch SW4 generates a display command signal of a cursor when it is depressed. Thegunsight 10 comprises amount 12, and ascope 13 and aforesight 14 which are held on thismount 12. Themount 12 is fixedly held on thebarrel 8 by engagingclaws barrel 8. In addition, themount 12 is so locked by a lockingclaw 17 formed in thebarrel 8 that it does not slip off the engagingclaws - Although the engaging
claws claw 17 are provided in the upper right front part in the longitudinal direction of the barrel 8 (on the right side as viewed from a muzzle 9), similarengaging claws claw 20 are provided in the upper left part of the barrel 8 (see Fig. 3). The engagingclaws claw 17 and the engagingclaws claw 20 are provided in positions symmetrical with respect to an optical axis of thebarrel 8. - As shown in Fig. 4, the
gunsight 10 may be detached from the engagingclaws claws gunsight 10 is mounted can be thus changed to the most suitable position depending on whether a user of the shooting scope is right-handed or left-handed. Consequently, it is possible to obtain a shooting scope significantly superior in operability. - As shown in Fig. 5, the
shooting scope 5 according to the present embodiment is generally used in a position close to, that is, spaced approximately 3 meters apart from thetelevision receiver 4. Consequently, if a sighting axis and the optical axis are parallel to each other, coordinates on the television screen of an extension line of the sighting axis and an extension line of the optical axis are considerably shifted. In the present embodiment, therefore, theshooting scope 5 is so constructed that when thegunsight 10 is mounted on thebarrel 8, thegunsight 10 makes a predetermined angle to the optical axis such that the sighting axis crosses an optical axis of a condenser lens 31 (see Fig. 6) provided within thebarrel 8 to form an intersection a predetermined distance (for example, approximately 3 meters) ahead of themuzzle 9. More specifically, thegunsight 10 is so selected that the sighting axis in a case where theforesight 14 is looked into from thescope 13 is slightly downward with respect to the bottom surface of themount 12, and is mounted on the upper part of thebarrel 8 and a position at an angle of 45° on the left or right side to the vertical axis passing through the optical axis. Consequently, whichever of the engagingclaws claws barrel 8 is a position where thegunsight 10 is mounted, the optical axis and the sighting axis can be made to cross (or concentrated on one point) on the screen of the television receiver 4 a predetermined distance ahead of themuzzle 9, thereby to make it possible to shoot the target accurately and with high precision. In addition, since thegunsight 10 is detachably constructed in the position at an angle of 45° on the right or left side to the optical axis, a player can surely aim at the target irrespective of the dominant hand, the dominant eye and the size of a player's face, thereby to make it possible to further improve the operability. When the distance between the shootingscope 5 and thetelevision receiver 4 is varied as represented bydotted lines 4' and 4" in Fig. 5 from the distance presumed (approximately 3 meters) as a result of inclining the sighting axis of thegunsight 10 from the optical axis of thebarrel 8 as described above, the coordinate position on the television screen of the extension line of the optical axis and the extension line of the sighting axis is shifted The present embodiment is so constructed that the shift of the coordinate position, that is, an error is corrected according to the distance between the shootingscope 5 and thetelevision receiver 4. - Fig. 6 is a block diagram showing the inner structure of the
shooting scope 5 shown in Fig. 1. In Fig. 6, theshooting scope 5 comprises alens 31, slits 32 and 33, aninfrared cut filter 34, alight receiving element 35, apre-amplifier 36, a high-pass filter 37, awaveform shaping circuit 38, an ANDgate 39, anOR gate 40, adriver 41, infrared LED (light emitting diode) 42, ANDgates monostable multivibrator 45, anoscillator 46, anoscillator 47, amonostable multivibrator 48, anencoder 49,monostable multivibrators 51 to 54, and aOR gate 55. - The
lens 31 is provided in the vicinity of themuzzle 9 and forms an image of a target displayed on thetelevision receiver 4 on thelight receiving element 35. Theslits slit 33 is selected to be smaller than the inner diameter of theslit 32. Theinfrared cut filter 34 is used for preventing infrared rays from being incident on thelight receiving element 35. Thelight receiving element 35 includes, for example, a photodiode, and detects a light signal from the target displayed on thetelevision receiver 4 and converts the same into an electric signal. A detection signal of thelight receiving element 35 is amplified by thepre-amplifier 36 and then, is applied to the high-pass filter 37. The high-pass filter 37 eliminates disturbance signals other than objective signals, for example, signals of sunlight, illuminating light and the like. An output of the high-pass filter 37 is subjected to waveform shaping by thewaveform shaping circuit 38 and is converted into a pulse signal and then, is applied to the ANDgate 39. - An output of the AND
gate 39 is applied to thedriver 41 through theOR gate 40. Thedriver 41 is used for driving theinfrared LED 42. Theinfrared LED 42 is provided inside of aninfrared device 11 and sends out an infrared signal to thereceiver 3. - A trigger signal based on an operation of the trigger switch SW1 is applied to the AND
gate 43 and is applied to the ANDgate 44 after being inverted. A continuous shooting signal based on the power supply/continuous shooting switch SW3 is applied to the ANDgate 44 and is applied to the ANDgate 43 after being inverted. A cursor signal based on the cursor switch SW4 is applied to theoscillator 47. A pause signal based on the pause switch SW2 is applied to themonostable multivibrator 48. Respective outputs of themonostable multivibrator 45, theoscillators monostable multivibrator 48 are applied to theencoder 49, Theencoder 49 encodes the respective signals inputted An output of theencoder 49 is applied to theOR gate 40. - The output of the
monostable multivibrator 45 is further applied to themonostable multivibrator 53 and is applied to themonostable multivibrator 51 through theOR gate 50. The output of theoscillator 46 is further applied to themonostable multivibrator 51 through theOR gate 50. Outputs of themonostable multivibrators monostable multivibrators monostable multivibrators gate 39 through theOR gate 55. - Description is now made of the operation of the
shooting scope 5. First, a player carries theshooting scope 5 on his shoulder, and looks into thegunsight 10 to sight a target on the television screen, At this time, thelens 31 collects light on an image on the television screen in the vicinity of the optical axis of thebarrel 8 and forms the image on thelight receiving element 35. Consequently, thelight receiving element 35 converts a light signal from the image in the vicinity of a portion to which themuzzle 9 is directed on the television screen (not the entire screen) into an electric signal and outputs the same. - The output of the
light receiving element 35 is subjected to amplification, noise removal and waveform shaping by thepre-amplifier 36, the high-pass filter 37 and thewaveform shaping circuit 38 and is converted into a pulse signal. Thelight receiving element 35 outputs a detection signal every time a scanning line, that is, a raster passes through a region where thelens 31 collects light on the television screen. Accordingly, an output of thewaveform shaping circuit 38 becomes a pulse train of raster pulses having a period according to the horizontal frequency of a television video signal (hereinafter referred to as a raster pulse train). This raster pulse train is shown in Fig. 7 (b). - The player depresses the trigger switch SW1 when sighting of the target displayed on the
television receiver 4 is terminated. Correspondingly, a trigger signal at a high level is outputted from this trigger switch SW1 and is applied to themonostable multivibrator 45 through the ANDgate 43. Themonostable multivibrator 45 outputs one pulse signal in response to this trigger signal. This pulse signal is applied to theencoder 49 to be encoded. As a result, theencoder 49 generates a trigger code as shown in Fig. 7 (a). This trigger code is applied to thedriver 41 through theOR gate 40. Thedriver 41 drives the infrared rays LED 42 on the basis of the trigger code applied. Consequently, a trigger code serving as an infrared signal is outputted from theinfrared LED 42, as shown in Fig. 7 (c). - The output pulse signal of the
monostable multivibrator 45 is further applied to themonostable multivibrators monostable multivibrators monostable multivibrators monostable multivibrators gate 39 through theOR gate 55. Consequently, the ANDgate 39 is opened in a time period during which this gate pulse is applied to pass the raster pulse train applied from thewaveform shaping circuit 38. The raster pulse train passing through the ANDgate 39 is applied to thedriver 41 through theOR gate 40. Consequently, the infrared LED is driven according to the raster pulse train, and the raster pulse train serving as an infrared signal is outputted from the infrared LED (see Fig. 7 (c)). - On the other hand, when the power supply/continuous shooting switch SW3 is slid to a continuous shooting position or when the cursor switch SW4 is depressed, a pulse signal having a constant period is outputted from the
oscillator encoder 49 outputs a trigger code for each constant period. On the other hand, themonostable multivibrators infrared LED 42 transmits the trigger code and the raster pulse train as shown in Fig. 7 (c) repeatedly for each constant period. - Fig. 8 is a block diagram showing the structures of the video game set 1 and the
receiver 3 shown in Fig. 1. In Fig. 8, thereceiver 3 comprises aninfrared pass filter 60, alight receiving element 61, apre-amplifier 62, a high-pass filter 63, awaveform shaping circuit 64, adecoder 65, and araster analyzing circuit 66. Theinfrared pass filter 60 is a filter for passing only infrared rags. Visible light is removed by thisinfrared pass filter 60, so that only the infrared signal from the above described infrared LED (see Fig. 6) is applied to thelight receiving element 61. Thedecoder 65 is a circuit for decoding the trigger code sent from theshooting scope 5 and applying the same to thevideo game set 1. Theraster analyzing circuit 66 is a circuit for extracting only a raster pulse from the signal detected by thelight receiving element 61. - The video game set 1 comprises an
input port 70, aCPU 71, a workingRAM 72, a videosignal generating circuit 73, ahorizontal counter 74, avertical counter 75, ahorizontal latch 76, avertical latch 77, a horizontal correctingcircuit 78, and a vertical correctingcircuit 79. Theinput port 70 is a circuit for applying an output signal of the above describeddecoder 65 to theCPU 71. TheCPU 71 is a circuit for performing various control operations on the basis of program data stored in aROM cartridge 2. The workingRAM 72 is a memory for storing various data required for control processing of theCPU 71. The videosignal generating circuit 73 is a circuit for generating a video signal for a game in accordance with the data applied from theCPU 71. - The
horizontal counter 74 counts video clock pulses (clock pulses in a dot cycle) applied from the videosignal generating circuit 73 and is reset by a horizontal synchronizing signal (HSYNC) applied from the videosignal generating circuit 73. Thevertical counter 75 counts a carry signal of thehorizontal counter 74 and is reset by a vertical synchronizing signal (VSYNC) from the videosignal generating circuit 73. Thehorizontal latch 76 latches a counted value of thehorizontal counter 74 in response to a latch pulse from theraster analyzing circuit 66. Thevertical latch 77 latches a counted value of thevertical counter 75 in response to the latch pulse from theraster analyzing circuit 66. The horizontal correctingcircuit 78 is a circuit for correcting an output of thehorizontal latch 76. The vertical correctingcircuit 79 is a circuit for correcting an output of thevertical latch 77. - Fig. 9 is a block diagram showing the more detailed structure of the
raster analyzing circuit 66 shown in Fig. 8. In Fig. 9, theraster analyzing circuit 66 comprises amonostable multivibrator 80, a D-type flip-flop 81, acounter 82, alatch 83, aROM 84, acomparator 85, ANDgates quinary counter 88, an output allowingmonostable multivibrator 89, an ANDgate 90, and an input stoppingmonostable multivibrator 91. - Description is now made of the operation of the
receiver 3 shown in Fig. 8. Theinfrared LED 42 in theshooting scope 5 transmits control data based on the infrared signal as shown in Fig. 7 (c) toward thereceiver 3. This infrared signal is applied to thelight receiving element 61 after unnecessary visible light is removed by theinfrared pass filter 60. An output of thelight receiving element 61 is respectively subjected to amplification, noise removal and waveform shaping in thepre-amplifier 62, the high-pass filter 63 and thewaveform shaping circuit 64 and then, is applied to thedecoder 65 and theraster analyzing circuit 66. Thedecoder 65 decodes the trigger code included in the infrared signal and transmits the result of the decoding to thevideo game set 1. Theinput port 70 outputs the result of the decoding of thedecoder 65 to theCPU 71. On the other hand, theraster analyzing circuit 66 analyzes a raster pulse train included in thewaveform shaping circuit 64, extracts the sixth pulse from the raster pulse train and outputs the same. - Referring now to Figs. 9 and 10, description is made of the more detailed operation of the
raster analyzing circuit 66. When the raster pulse train as shown in Fig. 10 is applied to themonostable multivibrator 80, themonostable multivibrator 80 is first initiated by a raster pulse a. Correspondingly, themonostable multivibrator 80 outputs one pulse having a predetermined pulse width. This pulse is delayed by 1 µs by the D-type flip-flop 81 and then, is applied to thecounter 82 as a clear signal. Consequently, thecounter 82 is cleared. Thereafter, thecounter 82 counts clock pulses having a frequency of 1 MHz. - When a raster pulse b is then inputted, the
monostable multivibrator 80 generates one pulse again. Thelatch 83 latches a counted value of thecounter 82 in response to this pulse. Thecomparator 85 compares a value latched in thelatch 83 with a value stored in theROM 84. TheROM 84 stores a value of "63". When the value latched in thelatch 83 is "63", that is, when the counter 82counts 63 clock pulses having a frequency of 1 MHz between the raster pulse a and the raster pulse b (when the period between the raster pulse a and the raster pulse b is 63 µs), thecomparator 85 outputs a coincidence signal at a high level. This coincidence signal passes through the ANDgate 86 and increments thequinary counter 88. - Subsequently, the raster pulses c, d, e, f, ... are sequentially inputted, to repeat the same operations as described above. Correspondingly, the
quinary counter 88 is incremented every time one pulse is inputted. When the pulse f is inputted, thequinary counter 88 outputs a carry signal, to initiate the output allowingmonostable multivibrator 89. Correspondingly, the output allowingmonostable multivibrator 89 outputs one pulse. As a result, the ANDgate 90 passes the pulse f and outputs the same to thevideo game set 1. At this time, the input stoppingmonostable multivibrator 91 is initiated by the output pulse of the output allowingmonostable multivibrator 89. Consequently, one pulse is outputted from the input stoppingmonostable multivibrator 91. Themonostable multivibrator 80 is inhibited from being initiated until the time when it is assumed that a raster pulse train in the succeeding frame is inputted in response to this pulse. Furthermore, the output pulse of the output allowingmonostable multivibrator 89 is applied to thequinary counter 88 through theOR gate 92 as a clear signal. As a result, thequinary counter 88 is cleared. - By the foregoing operations, the sixth pulse f in the raster pulse train is extracted and is applied to the
video game set 1. More specifically, in the present embodiment, the sixth pulse f located in an approximately central part out of the plurality of raster pulses included in the raster pulse train is extracted as a horizontal scanning line which is shot by theshooting scope 5. - The foregoing operations are performed when no noise is included in an input signal. When noise is included in an input signal by disturbance light from the exterior or the like, however, the period of pulses counted by the
counter 82 deviates from 63 µs. As a result, thecomparator 85 outputs no coincidence signal. Therefore, the ANDgate 87 passes the input pulse from themonostable multivibrator 80 and outputs the same to thequinary counter 88 through theOR gate 92 as a clear signal. As a result, thequinary counter 88 is cleared before outputting a carry signal. Therefore, the output allowingmonostable multivibrator 89 inhibits the input pulse f from being outputted. In the present embodiment, therefore, it is possible to prevent noise due to disturbance light or the like from being erroneously detected as a raster pulse. - Fig. 11 is a block diagram showing the more detailed structure of the horizontal correcting
circuit 78 shown in Fig. 8. In Fig. 11, the horizontal correctingcircuit 78 comprises acorrection value register 781, aROM 782, and anoperating circuit 783. - Fig. 12 is a block diagram showing the more detailed structure of the vertical correcting
circuit 79 shown in Fig. 8. In Fig. 12, the vertical correctingcircuit 79 comprises acorrection value register 791, aROM 792, and anoperating circuit 793. - Fig. 13 is an illustration showing a memory map of a ROM contained in the
ROM cartridge 2 shown in Fig. 8. In Fig. 13, the ROM contained in theROM cartridge 2 comprisesstorage areas 201 to 204. Thestorage area 201 stores a game program for game processing. Thestorage area 202 stores horizontal coordinate data of a target and a sighting mark to be displayed on thetelevision receiver 4. Thestorage area 203 stores vertical coordinate data of the target and the sighting mark to be displayed on thetelevision receiver 4. Thestorage area 204 stores a program for displaying the target on thetelevision receiver 4. - Referring now to a timing chart of Fig. 14, description is made of the principle of a detecting operation of a coordinate position which is shot by the
shooting scope 5 on the screen of thetelevision receiver 4. When thereceiver 3 receives a trigger code and a raster pulse train as shown in Fig. 14 (a), theraster analyzing circuit 66 extracts the sixth raster pulse included in the raster pulse train and outputs the same, as described above. This sixth raster pulse is applied to thehorizontal latch 76 and thevertical latch 77 as a latch pulse. Thehorizontal latch 76 and thevertical latch 77 latch the counted value of thehorizontal counter 74 and the counted value of thevertical counter 75 in response to this latch pulse. The counted values of thehorizontal counter 74 and thevertical counter 75 respectively correspond to a horizontal position and a vertical position of the raster. Consequently, the counted values latched in thehorizontal latch 76 and thevertical latch 77 correspond to a horizontal position and a vertical position which are shot by theshooting scope 5 on the screen of thetelevision receiver 4. More specifically, the number of horizontal synchronizing signals included in a period from a vertical synchronizing signal in a vertical scanning period immediately before the present vertical scanning period to the sixth raster pulse extracted by theraster analyzing circuit 66 is latched in thevertical latch 77. On the other hand, the number of video clock pulses included in a period T from a horizontal synchronizing signal in a horizontal scanning period immediately before the present horizontal synchronizing period to the sixth raster pulse extracted by theraster analyzing circuit 66 is latched in thehorizontal latch 76. - Referring now to flow charts of Figs. 15 and 16, description is now made of the operation of the
video game set 1. In the step S1 shown in Fig. 15, a sighting correction mode is first executed. This sighting correction mode is for displaying a sighting mark on the television screen before starting a game, and finding an error between a position which is shot by a player of the sighting mark and a central position of the sighting mark as a correction value. The details of such a sighting correction mode subroutine are shown in Fig. 16. - Referring now to Fig. 16, in the step S20, the
CPU 71 displays a sighting mark as shown in Fig. 17 in a central position of the screen of thetelevision receiver 4. This operation in the step S20 is achieved by theCPU 71 reading out the target display program stored in thestorage area 204 in theROM cartridge 2 and executing the same. The program then proceeds to the step S21. In the step S21, theoperating circuit 783 shown in Fig. 11 and theoperating circuit 793 shown in Fig. 12 respectively read out sighting coordinate data stored in theROMs ROM 782 stores a horizontal coordinate position "128" of a center point P1 of the sighting mark, and theROM 792 stores a vertical coordinate position "120" of the center point P1. The operatingcircuits - The program then proceeds the step S22. In the step S22, it is judged whether or not the trigger switch SW1 is turned on. If the trigger switch SW1 is turned on, the program proceeds to the step S23. In the step S23, the
horizontal latch 76 and thevertical latch 77 respectively latch horizontal coordinate data and vertical coordinate data corresponding to a point P2 which is shot by theshooting scope 5 on the television screen in response to the latch pulse from theraster analyzing circuit 66. In an example shown in Fig. 17, a horizontal coordinate position of the point P2 is "130", and a vertical coordinate position thereof is "123". The program then proceeds the step S24. In the step S24, theoperating circuit 783 operates a correction value in the horizontal direction. This operation of the correction value in the horizontal direction is performed by subtracting the horizontal coordinate data "128" of the center point P1 of the sighting mark from the horizontal coordinate data "130" of the point P2 latched in thehorizontal latch 76. The program then proceeds to the step S25. In the step S25, the correction value in the horizontal direction which is operated in the step S24 is written in thecorrection value register 781. The program then proceeds to the step S26. In the step S26, theoperating circuit 793 operates a correction value in the vertical direction. This operation of the correction value in the vertical direction is performed by subtracting the vertical coordinate data "120" of the center point P1 of the sighting mark from the vertical coordinate data "123" of the point P2 latched in thevertical latch 77. The program then proceeds to the step S27. In the step S27, the correction value in the vertical direction which is operated in the step S26 is written in thecorrection value register 791. Thereafter, the program is returned to the main flow shown in Fig. 15. - Referring to Fig. 15 again, if a game mode is selected in the step S2, the
CPU 71 reads out the game program from thestorage area 201 in theROM cartridge 2 and scrolls a background picture on thetelevision receiver 4 in the step S3. The program then proceeds to the step S4. In the step S4, theCPU 71 displays a target on thetelevision receiver 4. This display of the target is performed on the basis of the horizontal coordinate data and the vertical coordinate data of the target stored in thestorage areas ROM cartridge 2 and the target display program stored in thestorage area 204 therein. At this time, the display size of the target is varied on the basis of the type of target and the distance to the target. for example, even if targets are of the same type, the targets are so displayed that the shape of the target passing through a distant place is smaller than the target passing through a near place. The program then proceeds to the step S5. In the step S5, theCPU 71 reads an output of thedecoder 65 through theinput port 70. Subsequently, the program proceeds to the step S6. In the step S6, theCPU 71 judges whether or not the trigger switch SW1 is turned on, that is, the trigger code is detected by thedecoder 65. At this time, when it is judged that the trigger switch SW1 is not turned on, theCPU 71 is returned to the operation in the step S3 again. - On the other hand, if it is judged in the step S6 that the trigger switch SW1 is turned on, the program proceeds to the step S7. In the step S7, the operating
circuits shooting scope 5 on the basis of the horizontal and vertical coordinate data latched in thehorizontal latch 76 and thevertical latch 77 and horizontal and vertical correction values stored in the correction value registers 781 and 791. More specifically, theoperating circuit 783 subtracts the correction value stored in the correction value register 781 from the horizontal coordinate data latched in the horizontal latch 78 (horizontal coordinate data in a position which is shot by the player on the television screen), and outputs the result of the subtraction to theCPU 71. Similarly, theoperating circuit 793 subtracts the correction value stored in the correction value register 791 from the vertical coordinate data latched in the vertical latch 77 (vertical coordinate data in a position which is shot by the player on the television screen) and outputs the result of the subtraction to theCPU 71. The program then proceeds to the step S8. In the step S8, theCPU 71 displays the missile on the television screen on the basis of display coordinate data of the missile which is applied from the operatingcircuits - The program then proceeds to the step S9. In the step S9, it is judged whether or not the missile displayed in the step S8 hit the target displayed on the television screen. At this time, unless it hit the target, the program proceeds to the step S10. In the step S10, the
CPU 71 scrolls the target. The program then proceeds to the step S11. In the step S11, theCPU 71 scrolls a background picture. The program then proceeds to the step S12. In the step S12, theCPU 71 further reduces the display size of the missile so as to indicate that the missile flew to the distance without hitting the target. The program then proceeds to the step S13. In the step S13, theCPU 71 judges whether or not a constant time period has elapsed. Unless a constant time period has elapsed, the operations in the steps S9 to S12 are repeated again. On the other hand, if a constant time period has elapsed, the program proceeds to the step S14. In the step S14, theCPU 71 displays on thetelevision receiver 4 the fact that the missile missed the target. Thereafter, the program is returned to the operation in the step S3. - On the other hand, if it is judged in the step S9 that the missile hit the target, the program proceeds to the step S15. In the step S15, the
CPU 71 displays on thetelevision receiver 4 the fact that the missile hit the target. The program then proceeds to the step S16. In the step S16, theCPU 71 produces an explosive sound from thetelevision receiver 4. The program then proceeds to the step S17. In the step S17, theCPU 71 operates and displays the score. The program then proceeds to the step S18. In the step S18, theCPU 71 judges whether or not the game is over. If the game is not over, the program is returned to the operation in the step S3 again. On the other hand, it is judged that the game is over, the program proceeds to the step S19. In the step S19, theCPU 71 displays on the television receiver 4 a state where the game is over. Thereafter, the operations are terminated. - Fig. 18 is a block diagram showing the structures of a receiver and a video game set according to another embodiment of the present invention. The structure of the
receiver 3 is the same as the structure of thereceiver 3 shown in Fig. 8. On the other hand, the structure of the video game set 100 shown in Fig. 18 differs from the structure of the video game set 1 shown in Fig. 8 in that the horizontal correctingcircuit 78 and the vertical correctingcircuit 79 are eliminated. Alternatively, correcting operations performed in the horizontal correctingcircuit 78 and the vertical correctingcircuit 79 are performed by program processing by aCPU 71. Therefore,storage areas ROM cartridge 2. Thestorage area 205 stores a program for realizing correction processing which is executed in the step S7 shown in Fig. 15. In addition, thestorage area 206 stores a program for realizing an operation of a correction value which is executed in the sighting correction mode shown in Fig. 16. - Fig. 20 is an illustration showing a memory map of a working
RAM 72 in the embodiment shown in Fig. 18. As shown in Fig. 20, the workingRAM 72 comprisesstorage areas 721 to 726. Thestorage area 721 stores horizontal coordinate data in a shot coordinate position which is latched by ahorizontal latch 76. Thestorage area 722 stores vertical coordinate data in the shot coordinate position which is latched by avertical latch 77. Thestorage area 723 stores horizontal coordinate data in the shot coordinate position after being corrected which is operated by theCPU 71.
